请求时加上：getHC.setRequestHeader("Accept-Encoding","gzip, deflate");

解析时

String acceptEncoding = "";

     if(getHC.getResponseHeader("Content-Encoding")!=null)

      acceptEncoding = getHC.getResponseHeader("Content-Encoding").getValue();

     StringBuffer sb =new StringBuffer();

     log.debug("acceptEncoding:"+acceptEncoding);

     if(acceptEncoding.toLowerCase().indexOf("gzip") > -1)

     {

      //建立gzip解压工作流

      InputStream is = getHC.getResponseBodyAsStream();

      GZIPInputStream gzin = new GZIPInputStream(is);

      InputStreamReader isr = new InputStreamReader(gzin, charset); // 设置读取流的编码格式，自定义编码

      java.io.BufferedReader br = new java.io.BufferedReader(isr);

      String tempbf;

      while((tempbf=br.readLine())!=null){

       sb.append(tempbf);

       sb.append("\r\n");

      }

      isr.close();

      gzin.close();
